We have just taken up camping - our 13 year old T1 daughter is a born camper! She loves it and goes with guides/church and us. TBH, your daughter will enjoy the freedom of running around and getting lots of fresh air. Our biggest issue was swimming. My kids and I are waterbabies and we spent a lot of time in the pool. My daughter went swimming one day without me and I went to check on her. I'm glad I did because she was severely hypo. She signed in and put "diabetic" by her name. The lifeguard wasn't amused when she ripped open a can of coke poolside, while I explained what was going on. He did apologise later when he read the sign in book again. We took spare insulin ampoules with us and put them in the cool box - we had electric hook up so we had a kind of portable fridge. My girl is on pens and will happily whip 'em out and inject herself, regardless of the stares.
